Get the associated tooltip or NULL if none.


\membersection{wxWindow::GetUpdateRegion}\label{wxwindowgetupdateregion}

\constfunc{virtual wxRegion}{GetUpdateRegion}{\void}

Returns the region specifying which parts of the window have been damaged. Should
only be called within an \helpref{wxPaintEvent}{wxpaintevent} handler.

\helpref{wxRegion}{wxregion},\rtfsp
\helpref{wxRegionIterator}{wxregioniterator}


\membersection{wxWindow::GetValidator}\label{wxwindowgetvalidator}

\membersection{wxWindow::GetVirtualSize}\label{wxwindowgetvirtualsize}

\constfunc{void}{GetVirtualSize}{\param{int* }{width}, \param{int* }{height}}

\constfunc{wxSize}{GetVirtualSize}{\void}

This gets the virtual size of the window in pixels. By default it
returns the client size of the window, but after a call to
\helpref{SetVirtualSize}{wxwindowsetvirtualsize} it will return
that size.

\wxheading{Parameters}

\docparam{width}{Receives the window virtual width.}

\docparam{height}{Receives the window virtual height.}

\helpref{GetSize}{wxwindowgetsize},\rtfsp
\helpref{GetClientSize}{wxwindowgetclientsize}


\membersection{wxWindow::GetWindowBorderSize}\label{wxwindowgetwindowbordersize}

\constfunc{wxSize}{GetWindowBorderSize}{\void}

Returns the size of the left/right and top/bottom borders of this window in x
and y components of the result respectively.


\membersection{wxWindow::GetWindowStyleFlag}\label{wxwindowgetwindowstyleflag}

\constfunc{long}{GetWindowStyleFlag}{\void}

Gets the window style that was passed to the constructor or {\bf Create}
method. {\bf GetWindowStyle()} is another name for the same function.


\membersection{wxWindow::GetWindowVariant}\label{wxwindowgetwindowvariant}

\constfunc{wxWindowVariant}{GetWindowVariant}{\void}

Returns the value previously passed to
\helpref{wxWindow::SetWindowVariant}{wxwindowsetwindowvariant}.


\membersection{wxWindow::HasCapture}\label{wxwindowhascapture}

\constfunc{virtual bool}{HasCapture}{\void}

Returns {\tt true} if this window has the current mouse capture.

\helpref{wxWindow::CaptureMouse}{wxwindowcapturemouse},
\helpref{wxWindow::ReleaseMouse}{wxwindowreleasemouse},
\helpref{wxMouseCaptureLostEvent}{wxmousecapturelostevent}
\helpref{wxMouseCaptureChangedEvent}{wxmousecapturechangedevent}


\membersection{wxWindow::HasFlag}\label{wxwindowhasflag}

\constfunc{bool}{HasFlag}{\param{int }{flag}}

Returns \texttt{true} if the window has the given \arg{flag} bit set.


\membersection{wxWindow::HasMultiplePages}\label{wxwindowhasmultiplepages}

\constfunc{virtual bool}{HasMultiplePages}{\void}

This method should be overridden to return \texttt{true} if this window has
multiple pages. All standard class with multiple pages such as 
\helpref{wxNotebook}{wxnotebook}, \helpref{wxListbook}{wxlistbook} and 
\helpref{wxTreebook}{wxtreebook} already override it to return \texttt{true}
and user-defined classes with similar behaviour should do it as well to allow
the library to handle such windows appropriately.


\membersection{wxWindow::HasScrollbar}\label{wxwindowhasscrollbar}

\constfunc{virtual bool}{HasScrollbar}{\param{int }{orient}}

Returns {\tt true} if this window has a scroll bar for this orientation.

\wxheading{Parameters}

\docparam{orient}{Orientation to check, either {\tt wxHORIZONTAL} or {\tt wxVERTICAL}.}


\membersection{wxWindow::HasTransparentBackground}\label{wxwindowhastransparentbackground}

\constfunc{virtual bool}{HasTransparentBackground}{\void}

Returns \true if this window background is transparent (as, for example, for
wxStaticText) and should show the parent window background.

This method is mostly used internally by the library itself and you normally
shouldn't have to call it. You may, however, have to override it in your
wxWindow-derived class to ensure that background is painted correctly.


\membersection{wxWindow::Hide}\label{wxwindowhide}

\func{bool}{Hide}{\void}

Equivalent to calling \helpref{Show}{wxwindowshow}({\tt false}).


\membersection{wxWindow::InheritAttributes}\label{wxwindowinheritattributes}

\func{void}{InheritAttributes}{\void}

This function is (or should be, in case of custom controls) called during
window creation to intelligently set up the window visual attributes, that is
the font and the foreground and background colours.

By ``intelligently'' the following is meant: by default, all windows use their
own \helpref{default}{wxwindowgetclassdefaultattributes} attributes. However
if some of the parents attributes are explicitly (that is, using
\helpref{SetFont}{wxwindowsetfont} and not
\helpref{SetOwnFont}{wxwindowsetownfont}) changed \emph{and} if the
corresponding attribute hadn't been explicitly set for this window itself,
then this window takes the same value as used by the parent. In addition, if
the window overrides \helpref{ShouldInheritColours}{wxwindowshouldinheritcolours}
to return \false, the colours will not be changed no matter what and only the
font might.

This rather complicated logic is necessary in order to accommodate the
different usage scenarios. The most common one is when all default attributes
are used and in this case, nothing should be inherited as in modern GUIs
different controls use different fonts (and colours) than their siblings so
they can't inherit the same value from the parent. However it was also deemed
desirable to allow to simply change the attributes of all children at once by
just changing the font or colour of their common parent, hence in this case we
do inherit the parents attributes.


\membersection{wxWindow::InitDialog}\label{wxwindowinitdialog}

\func{void}{InitDialog}{\void}

Sends an {\tt wxEVT\_INIT\_DIALOG} event, whose handler usually transfers data
to the dialog via validators.


\membersection{wxWindow::InvalidateBestSize}\label{wxwindowinvalidatebestsize}

\func{void}{InvalidateBestSize}{\void}

Resets the cached best size value so it will be recalculated the next time it is needed.


\membersection{wxWindow::IsDoubleBuffered}\label{wxwindowisdoublebuffered}

\constfunc{virtual bool}{IsDoubleBuffered}{\void}

Returns \true if the window contents is double-buffered by the system, i.e. if
any drawing done on the window is really done on a temporary backing surface
and transferred to the screen all at once later.
